Abstract

Denote by script A sign(n) the family of isometry classes of compact n-dimensional Alexandrov spaces with curvature ≥ -1, and λ_k(M) the k^th eigenvalue of the Laplacian on M ∈ script A sign(n). We prove the continuity of λ_k : script A sign(n) → R with respect to the Gromov-Hausdorff topology for each k, n ∈ N, and moreover that the spectral topology introduced by Kasue-Kumura [7], [8] coincides with the Gromov-Hausdorff topology on script A sign(n).
